A cheap piezo alarm is no bargain if it’s
unreliable and fails to function when it’s
really needed. With all the cheap Chinese
Knock-Offs being sold, it’s hard to know
what to buy. So it’s important to buy from
someone who has made the effort to find and
sell only quality units. I am such a seller.
I’ve tested a lot of different mini alarms, and
found this alarm to have the best track record
for performance and reliability. And to further
maximize buyer satisfaction, I test every alarm
before I ship it. I’m proud to say that I’ve never
had an alarm returned because of defects or
buyer dissatisfaction.
This alarm is not a Chinese Knock-Off. It is
an Original and takes advantage of natural
component resonances to achieve maximum
sound output and keep the required operating
current as low as possible. That helps
insure the longest battery life when it’s
being powered by a battery.
This is the ABSOLUTE BEST Mini-Alarm I’ve
Found. Most alarms are made in China where
quality is not even an afterthought.
Compared to all the others I’ve tested, this
one is “THE BEST”. I’ve tested a lot of mini
alarms and this one comes closest to
consistently meeting the advertised specs.
And it’s the most reliable with the lowest
out-of-the-box defect rate. With many
Chinese made alarms there is wide variation
in sound output, which means most of them
failed miserably to produce their advertised
loudness. So if Quality, Reliability, and
Loudness are more important to you than
finding the cheapest price, you have found
what you’re looking for here!
For Getting the Maximum Sound Out Of This
Alarm, You’ll Need a Good 12V Power Adapter.
If you need such an adapter, I can recommend
a good power adapter to you that I have
personally tested on this alarm.
If Shopping for a “Top Quality” Alarm, it’s
important that you take time to read the
next paragraph below.
Proven Quality and Reliability, Let me
Explain how I know: I have purchased a lot
of different piezo alarms to sell on eBay
while seeking a unit that is loud, reliable,
and consistent in quality and performance.
As you probably suspect, most other piezo
alarms are made in China where quality
control isn’t even an afterthought. But
these alarms are different. I have yet to
have any complaints with these alarms. All
the other Chinese made alarms I tried had at
least a 5% Failure Rate; and the performance
of most of those was poor to mediocre at
best, with a majority of them failing
miserably to produce the advertised sound
intensity. The design and manufacturing of
most the Chinese made alarms also left a
great deal to be desired, with some even
having loose parts inside that rattled,
and/or other imperfections in the case and
assembly. But at last, my search is over.
This is the Best Alarm I’ve Found, and it
Meets all my requirements for Quality and
Performance. I’m proud to offer this High
Quality Alarm to my eBay customers!
This alarm can be used in your own home
projects when used with sensor switches or
controls that connect it to a 6 to 15 volt
external power supply …or… It can also
be added to existing security systems that
provide 6 to 15 Volt connections for
additional alarms. In such cases, if the
existing alarm system provides a Voltage
output for additional alarms, just connect
it observing the proper polarity. If the
existing alarm system just provides a relay
contact closure, you will need to add a 12
volt power supply in series with this alarm
when making the connection (observing proper
polarities, of course). Note: This alarm is
not compatible with alarm systems that
generate their own alarm signal and provide
an audio output connection for additional
speakers or horns.
Warble Definition:
Similar to a Siren, the pitch of the sound rises and falls
linearly in a repeating pattern.
It produces a Very Loud, Medium-Slow Warbling
type sound, and it only draws about 110ma at
12 Volts. The unit I tested even ran on as little
as 6 Volts at a somewhat reduced volume level.
I don’t know if all units will perform at voltages
this low or not, but I will be happy to test a unit
for you at what ever voltage you request. Just
send me an email before you buy specifying the
voltage you would like me to test the device at.
Please Note:
The maximum advertised sound level will only
be produced when powered by a 12V source.
Lower operating voltages will result in lower
sound levels being produced. This is true of all
piezo alarms, not just this one. That’s just the
way it is being subject to the Laws of Physics.
Also Note:
This is just a Sounder and requires a
connection to a voltage source. It does not
have a built-in triggering mechanism,
battery, or automatic shut-off.
Usage Considerations:
Since this is a Mini Alarm having Low Power
Requirements and a Small Diaphragm, this
alarm may not be suitable for outdoor use
where a large coverage area is desired or
the sound needs to carry great distances.
BEWARE:
It’s common for Chinese manufacturers
and other sellers to make False Claims
on the DB Sound level produced and
the Watt rating of the amplifier that is
producing the sound. But here is how
you can tell when false claims are being
made:
Find the listed current rating of the
alarm in the ad and multiply that value
(in amps) times the alarm’s maximum
voltage rating. If your calculation is much
less than the seller’s stated Watt rating,
you cannot trust the specs the seller has
listed for his alarm. If the seller’s ad does
not list the alarm’s operating current, that
can also be a clue that the seller does not
want you to know the truth about his alarm.
This alarm’s power consumption is about
1.32 Watt (.11 Amp x 12V = 1.32 Watt).
That is typical for piezo mini alarms
of this size, yet you will find some
eBay sellers advertising these kind of
mini alarms as 10 Watt, which is a
HUGE LIE! Know what you’re buying
and if you can trust who you’re buying from.
Sorry, No Local Pickups!
